Has anyone replaced their front bushings for their Hotchkis sway bar? I brought my car to the dealer for a thump thump noise and they told me that my bushings are not bushings anymore, they're toast! So, does Hotchkis make a better bushing than they provide in their packages, or does another company make Polyurethane bushings for the Hotchkis set-up??? Please, any help would be greatlyappreciated. These bushings became toast after about 6000-7000 miles. I had them installed in June.
